Micropachycephalosaurus

Micropachycephalosaurus is a genus of small, bipedal dinosaur that lived during the Late Cretaceous period, approximately 75 million years ago. It was a member of the pachycephalosaurid family, which is known for its thick-skulled members. Micropachycephalosaurus was a small dinosaur, with an estimated length of about 2 meters (6.5 feet) and a weight of around 20 kg (44 lbs). Its skull was distinctive, with a wide, rounded dome on top and a relatively short snout. The dome was made up of thick, layered bone, which likely provided protection for the brain during head-butting behavior. Micropachycephalosaurus is known from only a few fossil specimens, which were discovered in China.
